主語從句Author:Miss.Liu【語法導(dǎo)圖】主語從句主語從句的概述不同引導(dǎo)詞引導(dǎo)的主語從句主語從句that引導(dǎo)的主語從句whether/if引導(dǎo)的主語從句連接代詞引導(dǎo)的主語從句連接副詞引導(dǎo)的主語從句注意事項概述在句中起名詞作用的各種從句統(tǒng)稱為名詞性從句。根據(jù)它們在句中的語法功能，這類從句又可分為主語從句、賓語從句、表語從句和同位語從句。在主從復(fù)合句中，充當(dāng)主語的從句叫主語從句。主語從句的引導(dǎo)詞有：①從屬連詞：that,whether,if等。②連接代詞：who,whose,whom,which,what,whoever,whomever,whichever,whatever等。③連接副詞：when,where,why,how等一、that引導(dǎo)的主語從句1、that在主語從句中不充當(dāng)句子成分，無含義，只起連接作用，通常不能省略。Eg:Thatshewonthegamemadeusveryhappy.她贏得了比賽令我們非常高興。Thattheorymustgohandinhandwithpracticeisaprincipleweshouldalwayskeepinmind.理論必須與實踐相結(jié)合是一項我們應(yīng)該永遠牢記的原則。Eg:Itisobviousthatyouhavemadeabigmistake.很明顯你犯了個大錯。2、由于主語從句過長，為保持句子平衡，常用it作形式主語，而將that引導(dǎo)的主語從句后置，常見的此類句型有：①It+be+形容詞（obvious,natural,certain,surprising,necessary,likely,possible等）+taht從句②It+be+名詞（詞組）（nowonder,anhonour,agoodthing,nosurprise,apity等）+that從句

Eg:Itisapitythatyoudidn’tattendthelectureyesterday.很遺憾你昨天沒參加這個講座。③It+be+過去分詞（said,reported,considered,thought,expected,decided,announced,suggested等）+that從句

Eg:Itisreportedthatnopassengerswerehurtintheaccident.據(jù)報道沒有乘客在此事故中受傷。④其他常見固定搭配：Itdoesn’tmatterthat.........是無關(guān)緊要的Ithappensthat...碰巧......Itturnedoutthat...結(jié)果是......Itoccurredtosbthat...某人突然想到......二、whether/if引導(dǎo)的主語從句whether/if在從句中只起連接作用，在句中不作成分，意為“是否”，且不可省略。whether引導(dǎo)的主語從句既可以放在句首，也可以放在句尾，但if引導(dǎo)的主語從句只能放在句尾，前面需用it作形式主語。Eg:Whetherthesportsmeetingwillbeheldisnotcertainnow.運動會是否會舉行還不確定。Iwonderifheisreallysincere.我想知道他是否是真誠的。二、連接代詞引導(dǎo)的主語從句連接代詞who,whose,whom,shich,what,whoever,whichever等引導(dǎo)主語從句時，既起連接作用，也在從句中充當(dāng)主語、賓語、表語、定語等成分，且不可以省略。Eg:WhatIreallyneedatpresentisyourunderstandingandsupport.我現(xiàn)在真正需要的是你的理解與支持。Whichcaryouwillchoosetobuymakesnodifference.你會選擇哪臺車沒什么區(qū)別。四、連接副詞引導(dǎo)的主語從句連接副詞when,where,why,how等引導(dǎo)主語從句時，在從句中既是連接詞，又作狀語。其中when作時間狀語，where作地點狀語，why作原因狀語，how作方式狀語。連接副詞引導(dǎo)的主語從句，也常用it作形式主語。Eg:Wherehelivesisnotknowntoanyone.他住在哪沒有人知道。Whenwewillhaveasportsmeetinghasnotbeendecidedyet.我們何時舉辦奧運會還美譽決定?！就叫【殹?.__________isapitythatyourparentsdidn’tallowyutofollowus.2.__________isagreedthatwewillsetofftomorrow.3.__________partofthecountryhewilltarveltoneedsdiscussing.4.Yoursupportisimportanttoourwork.__________youcandohelps.5.__________weunderstandthingshasalottodowithwhatwefeel.6.__________isfantasticabouthistoryisthewayitbrodensourhorizens.It
